* Some of the end-of-battle quotes. In fact each of the 37 potential combinations (35 threes and two early-game duos) of characters [[https://youtu.be/rGGf78H2fck has an amusing post-battle quote.]] Most of them are pretty good and they don't repeat often enough to become grating. Here's one of the most hilarious:
--> '''Melia''': Here Riki, Riki, Riki... May I stroke your fur please?\\
'''Riki''': Melly always welcome!\\
'''Reyn''': Me too! Me too!\\
'''Riki''': Reyn give one biscuit for every stroke!\\
'''Reyn''': Hey! Why am I the only one who has to give you stuff!?\\
'''Reyn''': You can't have a rainbow without Reyn, baby!\\
'''Melia''': Dunban, I think you need to have a talk with Reyn.\\
'''Dunban''': No, let's pretend it didn't happen.\\
'''Riki''': Riki wish Melly was real big sister\\
'''Melia''': Aww, what about Sharla?\\
'''Riki''': Sharla more like mama. One mama enough.\\
'''Sharla''': Now wait just one minute!\\
'''Melia''': He's [Riki] so cuddly I could almost cuddle him to death.\\
'''Dunban''': Riki may be the softest of all Nopon.\\
'''Riki''': Riki suddenly feel afraid...[[note]]It becomes HilariousInHindsight if you did the Heart-to-Heart 'A Mysterious Sanctuary' first, and got all possible hearts, where Riki says that Melia can "stroke [his] fur and cuddle [him] anytime!"[[/note]]\\
'''Reyn''': Just goes to show, brawn is better than brains.\\
'''Sharla''': Oh, I can't let that one slip by.\\
'''Melia''': The head, shoot him in the head!\\
'''Reyn''': What, what did I say?\\
'''Reyn''': Sharla, did you see me?! Did you see what I did?\\
'''Sharla''': Oh, I wasn't really looking.\\
'''Reyn''': Oh come on! That ain't fair!\\
'''Shulk''': ''*laughs*''\\
'''Reyn''': Like they say, when the going get going, the tough get tough!\\
'''Riki''': Haha! Even Riki know that not right!\\
'''Dunban''': Reyn, what are you babbling on about?\\
'''Shulk''': I wish I had a brother or sister. ''(referring to Fiora and Dunban)'' You guys are like a real family.\\
'''Fiora''': Well, you're basically like our baby brother.\\
'''Shulk''': What?! "''Baby''" brother?!\\
'''Fiora''': ''*laughs*'' Be careful what you wish for!\\
'''Riki''': Thanks to Riki's sidekicks, we win!\\
'''Reyn''': ''What?!'' Who are you calling 'sidekick'?\\
'''Riki''': No see anyone else... must be you!\\
'''Reyn''': Stupid furry volleyball... I'm gonna-\\
'''Shulk''': ''*laughs*'' Reyn, you're such an easy target!\\
'''Shulk''': ''(referring to Fiora and Melia)'' Wow, when did you two get so tough?\\
'''Fiora''': ''What?!'' Just because we're girls, we're supposed to be wimps?! How rude!\\
'''Melia''': Quite. I'm afraid you have much to learn about the fairer sex, Shulk.\\
'''Shulk''': Ugh... Why do I get the feeling that mastering the Monado is gonna be easier?\\
''(Fiora and Melia both laugh)''
* Some of the item descriptions are also pretty funny, for example
--> '''Rotten Meat''': Best avoided. Sold with a certificate guaranteeing gastroenteritis.
* As a gameplay example: [[OhCrap seeing a vision of a really powerful enemy attack]]... [[EpicFail missing.]] Sometimes you ''don't'' want to change the future!
* Put Reyn in the party lead and jump around for a while. One of his voice clips for jumping is "alley-oop!", which is just so unexpected compared to everyone else's that you can't help but laugh.
* After the Ether Mines, Shulk and Reyn stand near a cliff edge and commiserate over not finding Metal Face. [[SpeakOfTheDevil Guess whose enormous form suddenly rises over the ridge?]]
--> '''Metal Face:''' Hope I'm not interrupting...
* Melia's introduction starts with the wrong foot when a recently sent back to conciousness Melly slaps Shulk clean in the face. Cue awkward apology.
-->'''Melia:''' I'm sorry. I did not have the pleasure of coming into contact with a male Homs.\\
'''Dunban:''' "Coming into contact"? *Laughs*\\
'''Reyn:''' Hey, Shulk; you're creeping this lady out! *Grin/thumbs up combo*\\
'''Shulk:''' Shut up, Reyn!\\
'''Melia:''' This large one is far worse.\\
'''Reyn:''' Me!?\\
[=*=]Shulk and Sharla laugh*
* Melia ''in general'' can be pretty funny. One of her after-battle quotes is a MortalKombat reference!
--->'''Melia:''' Flawless victory.
* When Melia is accepting a quest and Sharla is in the party, Sharla can tell her to be more casual. Melia tries, but just ends up being {{Adorkable}}.
---->'''Melia:''' G-gotcha...friendio! Leave it to us...m-mate!
* Riki's introduction, full stop. [[http://www.youtube.com/watch?v=CCpybPtSqig Words cannot do it justice]].
* When the party first enters the High Entia Tomb, Reyn [[WhatDoesThisButtonDo presses a button out of sheer curiosity]], inadvertantly activating a trap meant to prevent "uninvited guests" from visiting the tomb. Naturally, everyone chews him out for it. The face Riki made while he and the rest of the party fell down the hole after Reyn pushed said button is also funny.
* Near the end of the dungeon, Reyn complains about how long it's taking and Alvis snarks about how they could have gotten there faster if ''somebody'' didn't push the button, which is funny enough [[TheComicallySerious coming from Alvis as-is]] and becomes even funnier when you learn [[spoiler:just what Alvis is.]]
* Even when Metal Face is in the middle of an invasion and being chased by tons of High Entia defense drones, he still finds time to crack a bad joke.
-->'''Metal Face:''' This fly infestation is beginning to ''bug'' me! Ha ha!
** He later refers to the Sky Rays as "ginormous... ''things''".
* Late into the game, while things slowly get dark as the plot advances, there are still noteable moments to make you smile. Like when the party [[spoiler: falls onto the flying Junks, Dickson drops down to greet Shulk and Fiora with open arms...[[https://www.youtube.com/watch?v=nTdODpdlx6U#t=4m35s and Reyn with his feet.]] ]]
* Some cutscenes can do this depending on the player's preference in equipment, because when things are supposed to be completely serious you can't help but crack a smile because Dunban is [[FanService half-naked,]] Melia looking [[BadassAdorable astonishing]] with glasses, or Riki making priceless facial expressions in the background [[FunnyBackgroundEvent while carrying a ridiculous biter with him.]]
* The end cutscene has a few good scenes, from the fishing antics between Reyn and Riki, to Shulk awkwardly pretending not to notice that [[spoiler: Fiora got her old body back, changing the subject to her ''[[DidYouGetANewHaircut hairstyle]]'' of all things.]]
* The end of the Red Pollen Orb sidequest chain, where you confront [[spoiler: Bana the Nopon. You promptly fight him as a [[LethalJokeCharacter Unique Monster]] to the tune of ''[[SeriousBusiness Tragic Decision]]'']]. He's also at a higher level than [[spoiler:Yaldabaoth, which is, according to Egil, the ''strongest Mechon ever constructed''. Yes, this lone Nopon riding a pterodactyl is ''more dangerous'' than the most powerful Mechon ever.]]
* There's a small section of Satorl Marsh filled with assorted Bunnits. Wander around there too much after the events at Mechonis Core, and you might just encounter [[KillerRabbit one of the game's five superbosses]].
* One of the achievements imply that Riki loves to eat bugs. The achievement can be gotten simply by giving 30 bugs as presents to other party members with Riki as the giver.
* Dunban hates Ether Plums with a passion. This is represented in-game as this being one of the things that would cause the most drop of affinity towards a party member if they were to give him one... [[VideoGameCrueltyPotential and an achievement for doing this]].
* One of the Heart to Heart moments involves a scene between Sharla and Reyn in the Refugee Camp on Bionis Leg. The options that will net you the most hearts involves Sharla teasing Reyn.
* Many of the quests found within Frontier Village are written from the quest giver's point of view. Even the messages given once you've completed the quests are written from their point of view. Their reactions for you completing some of their quests are priceless due to simple-like personalities.
* One of the Frontier Village quests involves finding a hook a Nopon lost because he wanted to try and catch Deinos. Once you've completed the quest, it's revealed that he's too light to be able to anchor himself onto the ground once he manages to get one hooked.
* Kuriku the young Nopon's personality description states that he's a [[ShapedLikeItself Spherical Nopon]].
* Melia's Starlight Kick. It's a useful art that can (finally) allow you to force topple on enemies. However, seeing tiny little [[SquishyWizard Melia]] kick something three times her size so hard she ''knocks it to the ground'' is hilarious.
-->'''Melia:''' ''"En Garde!"''
* One of the Heart-to-Hearts between Shulk and Riki involves Riki bathing within the Jakt Geyser of Valak Mountain while treating it as a hot spring. Do it right by choosing the options that give off the most hearts, and Riki will try to beckon Shulk to join in, only to get blasted off-screen by the geyser's eruption.
-->'''Riki:''' ''Do not worry, Shulk! Shulk will like water same as Riki.''
-->''The geyser erupts, launching Riki away.''
-->'''Shulk:''' ''Aaah! The geyser’s blown him away! Time for me to make a run for it! Sorry, Riki!''
* If you have Riki in your active party but you're not playing as him, Riki may confirm orders given to AI party members with "Aye aye... nose, mouth!"
* Some of Riki's battle interactions with Dunban are worth a laugh.
-->'''Dunban:''' ''I can feel my power returning to me!''
-->'''Riki:''' '''Power' sound like 'sour'! Sweet better!''
* The ending has a scene involving Reyn, Sharla and Riki fishing. When Reyn failed to catch a single fish, Riki started complaining about him not catching any fishes because Riki's hungry (and that Reyn must be the one to do so, not him). This prompted Reyn to remind him of his wife and children in an attempt to convince Riki to fish. This ended up backfiring on him due to Riki ComicallyMissingThePoint by demanding Reyn to try and catch as many fishes as possible.
* An alternate dialogue route in the Heart to Heart "A Scene Revisited" between Reyn and [[spoiler:Fiora]] reveals that ''Reyn once tried to use the Monado to cut vegetables.'' Reyn tried to use the only hope against the Mechon, an ancient reality-warping destiny-changing sword [[spoiler:containing the soul of a god that created the universe]], ''[[MundaneUtility to cut vegetables]]''.
* The Heart-To-Heart moment "Fiora's Cooking" has Reyn and Fiora discuss Fiora's cooking (or, in particular, the food she makes for Shulk). The choices that gives off the most hearts are both related to Reyn wanting to eat some of Fiora's food.
* The choices that give the most hearts within the Heart-To-Heart moment "Life's Hard for a Heropon" eventually culminates in Riki proposing to move him and his entire family into Dunban's house. The thing is, Riki has lots of children to take care of and Dunban's house is actually quite small. When Dunban calls him out of it, Riki then proposes to make it bigger. Dunban then teasingly ask if he's going to get a loan to help make it bigger. (Riki's backstory is that the only reason why he was "chosen" as the Heropon is because of the huge debt he has to the village).
* If you chose the right answers within the Heart-to-Heart moment "The Forefathers", Riki would suggest a plan to destroy telethia that involves using bait to lure them into a pit trap and bury them alive. At the end, Fiora thinks to herself, "If the Telethia were that stupid, nobody would be scared of them!"
* A cutscene reveals how Colonel Vangarre survived [[spoiler:Sword Valley being picked up by the moving Mechonis]] He's being hold by a fellow Homs soldier who is, in turn, holding onto a Nopon aerial unit (which consists of a few Nopon soldiers riding a Pterix). What DrillSergeantNasty Vangarre yells in response to this is what makes it funny, threatening the soldier with lots of pushups if he were to drop him.
* The Heart-To-Heart "The Legend of the Spider" reveals that Reyn got his phobia of spiders by Shulk putting one in his shoe as a prank. The Heart-To-Heart also reveals Shulk did that prank in response to Reyn's prank of putting a caterpillar in his sock drawer, with the implication that it gave Shulk a similar phobia towards caterpillars.
* It's possible for Riki to wield fish as his weapons during battle. Comes in two varieties: the full fish, called the "Fish Biter" in-game, and an eaten fish (with its entire body save for its head being a skeleton), called the "Banquet Biter" in-game.
* A funny little piece of GameplayAndStorySegregation: if you have Shulk in your party but not actively controlling him, it is possible (and, considering his Monado Arts, more than likely) for you to warn ''him'' of an incoming vision of the future.
* The Streetpass Puzzle Swap picture depicting this game shows three Nopon in front of the Monado. You may just assume the animated picture's just depicting two random Nopon playing with each other... until the third Nopon lying by them gets up. Then you realize that the third Nopon happens to be Riki himself.
* One of Riki's heavy armor styles is ''completely'' covered with nasty-looking spines. Outfitting Riki in a full set of this makes him look less like a cuddly Nopon and more [[http://vignette1.wikia.nocookie.net/xenoblade/images/4/4d/Riki_wants_hugs.jpg/revision/latest?cb=20150331013257 like a giant spiky steel ball]]... or a bouncing durian. Becomes even better in cutscenes where a character is cuddling Riki, or [[LivingCrashpad his introduction]] in NewGamePlus.
* The simple fact that, in terms of levels, some tiny little spiders living in [[BonusDungeon the extended Tephra Cave]] are vastly more powerful than the FinalBoss, who is [[spoiler:a literal god, not to mention the one responsible for ''creating'' all those creatures that are inexplicably more powerful than himself. He really wound up on the bad side of the whole "Can God create a rock so massive even He cannot move it" paradox, huh?]]
* NewGamePlus keeps all your equipment from the last run, even in cutscenes. This can make some early-game cutscenes rather odd, with Dunban, Dickson, and Mumkhar talking about some random sword as if it were the Monado, Shulk relaxing in a valley while wearing titanic metal armor, or the aforementioned Riki introduction. Depending on what armor she was wearing, [[spoiler:Fiora also might not quite fit right into Face Nemesis.]]
